摘    要:对钽表面渗氮的固-气界面反应过程进行了热力学和动力学分析,从到理论预测了各种参数(压力、气体、组成、温度、电参数等)对表面过程的影响,并借助于等离子体,在较你廿获得由层与N在TA中的固溶体组成的表面硬化层,层为六方晶系的Ta6N2,57和/或非昌态。通过调整工艺参数有效地抑制了钽表面氧的渗入和Ta2O5的形成,使得离子渗氮后,仍保持较低的表面粗糙度。

关 键 词:钽 离子渗氮 表面过程

Abstract:The reaction process on the surface of solid gases during nitriding of tantalum was discussed thermodynamically and dynamically. The effects of technical parameters such as pressure, temperature, electrical current density and voltage on the surface process were analyzed theoretically. The nitriding layers on tantalum surfaces with high hardness and better roughness were obtained with the help of plasma at low temperature. The layers were composed of the solid solution of tantalum and surface layers, which are amorphous phase or/and compound Ta 6N 2.57 .
Keywords:tantalum  ion-nitriding  sarface process
